......As a loyal supporter of the anti-smoking movement, Jiang Yaqi vows to fight this evil idea to the end, yes, it is evil!

But just as she was about to sweep the scum of the design world in front of her out of the house, her arm was slightly touched.

"Director Zhou?" Jiang Yaqi turned her head a little dissatisfied, she hadn't forgotten that this guy was a genuine old smoking gun, the culprit of the company's air pollution.

Sure enough, Zhou Xinghua glanced at Zhao Ping'an with interest, and said with a smile: "This idea is ingenious, and from a business point of view, it is not a good design." ”

"That's it? Okay design? Jiang Yaqi's eyes widened, she looked at him incredulously, and after seeing that he was unmoved, she said angrily: "The Tao is not the same!" ”

Seeing the smell of gunpowder in the room, another interviewer named Zhang Weiming hurriedly started the round, "Okay, young man, give you the opportunity to enter the second round of interviews, please explain the specific implementation plan and product design principles." ”

"And you want to explain the principle?"

Zhao Ping'an suddenly felt that his head was big for a while, and the plan was simple, but how to explain the principle? In fact, there is no principle at all in his design, just a simple fusion of two very common things, why don't you ask your buddy to tell you the chemical equation of anger?

I guessed in my heart that this second round of assessment should be about knowledge, and Zhao Ping'an only hated the chemistry teacher for dying early! Well...... Wait, chemistry!

For no reason, Zhao Ping'an actually remembered the 'Universe Low Chemical Skill Book', and what was even more strange was that as he thought about it, the blue game interface that seemed to be visible only to him appeared in front of him again, and a line of words was displayed in the previous dialog box:

[Detected that the host is facing the crisis of knowledge exhaustion, should you choose to learn the warehouse items - the cosmic low-level chemistry skill book?] 】

Damn, you can detect this?

Zhao Ping'an secretly admired the magic of this black technology game at the same time, almost without thinking about it and chose to learn, at this time it doesn't matter if it is a game, with his years of professional experience, the general game settings are higher than reality and born out of reality, maybe you can really pick up a few chemical terms to deal with?

As the cosmic low-level chemistry skill book in the warehouse disappeared, a vision struck! Zhao Ping'an only felt that an incomparably complex message was like a spring, constantly drilling into his mind, and that feeling was like a withered flower bathed in rain and dew, and the dry riverbed ushered in rain, which made his whole person a little fluttery, wrapped in a strong sense of satisfaction.

These things only happened in an instant, and just when the three interviewers wanted to urge him, Zhao Ping'an raised his head suddenly, and the fire of wisdom in his eyes overflowed!

He probably knows by now that he's in a big deal!

Possessed by some unknown black technology!

Well, since you can't resist it, then choose to accept it, and next, buddy is going to start the Xueba mode!

The corners of his mouth hooked up a touch of evil arc, and Zhao Ping'an said slowly: "My design is to put it bluntly, it is to combine matches and cigarettes into one, to put it professionally, it is to create a friction surface on the cigarette box, and then design another friction surface on the cigarette butt, so as to achieve the purpose of ignition, no longer rely on other ignition equipment." ”

Speaking of this, after Zhao Ping'an cleared his throat, he accelerated the speed of his speech in vain, "What I use is the principle of physical friction heat generation, and then use the chemical activity of strong oxidants and reducing agents to achieve the purpose of friction fire, the main components of the friction surface of the cigarette box are non-toxic ignition agent red phosphorus, and flammable diantimony trisulfide; The substances on the friction surface of the cigarette are potassium chlorate and tetraphosphorus trisulfide, well...... Sulfur can also be used instead of phosphorus trisulfide, so that the ordinary frictional heat will not make the drug surface react, safer, only when the phosphorus layer of the cigarette box is scratched, the frictional heat will make the sulfur react with potassium chlorate, release more heat energy, and promote the chemical substances in the cigarette butt to react and ignite. ”

Zhao Ping'an completely ignored the surprised expressions of the three interviewers, pulled over the mobile whiteboard beside him, picked up a marker, and wrote a string of characters on it:

2KClO3+ 3S──→2KCl + 3SO2+ 1137kJ

Then he continued: "This is the reaction process of the firing principle, but this chemical reaction is too violent, and the firing is too violent, which is not conducive to use. In order to control the ignition speed, some chemical neutralizers need to be added to the friction surface of the cigarette to make the ignition of the medicine surface slow and stable; In addition, it is best to replace sulfur with starch, shellac, etc., and add some spices, so that the irritating gas SO2 will not be produced when burned, and it can emit a fragrance, which will make the cigarette taste better. ”

Jiang Yaqi was stunned and looked at the young man in front of him who was talking eloquently, for no reason there was a ridiculous illusion that he had traveled to the high school chemistry class, and the young man in front of him was the teacher.

Does this guy really study design?

She couldn't help but swallow her saliva and asked weakly, "Are you sure this won't be poisonous?" Cigarettes are for people to smoke after all? ”

Zhao Ping'an originally wanted to continue, but at this moment, he only felt that the knowledge in his brain was about to overflow, and he was really a little reluctant not to shake it off and show it off.

After being interrupted by Jiang Yaqi's thoughts, he said angrily: "This young lady, are you kidding me?" Smoking is harmful to health, which of the eight big words is not on the cigarette box? They even asked me if I was poisonous? ”

"You!"

Without waiting for Jiang Yaqi, who had dry skin and was obviously a little lacking in love, to get angry, Zhao Ping'an asked rhetorically: "Is carbon dioxide still poisonous?" Don't we suck the same every day? I didn't see anyone poisoned. ”

"......" Jiang Yaqi never imagined that the top student of Jiao Tong University would one day be refuted speechlessly by a student who participated in the interview.

Fortunately, Zhao Ping'an also knew the current situation, and accepted it when he saw it, and did not go to the sky, and added in a timely manner: "In fact, as long as it is made according to my design, it is basically non-toxic." ”

"I have a question." Zhou Xinghua seemed to be smiling forever, with a smile on his face at the moment, and asked thoughtfully: "Will this increase the manufacturing cost of cigarettes?" ”

"Smack! Yes, to the point! Zhao Ping'an slapped his palm and glanced at him with a very relieved look.

Zhou Xinghua was made to cry and laugh by him, and always felt that there was something wrong with the painting style, who is interviewing who now? But then again, this kid does have two brushes, and it's rare to learn design with such a deep foundation in chemistry.

"The price of a box of sulfur-free aromatic matches on the market is 5 cents, which is still retail, and the manufacturing cost is only 2 cents, and the average consumption level of Chinese smokers for a box of cigarettes is 15.68 yuan, so ...... To put it mildly, who the fuck cares about those 2 cents? ”
